Method for rendering a multimedia content and a navigation interface on a screen

Abstract

A method for managing, in a reader terminal, streaming of a televisual content, called the main content, and of a navigation interface concomitantly from a telecommunication network, the navigation interface has regions including contents representative of real-time televisual contents available for selection, which contents are called secondary contents. The method includes the following steps, in the multimedia-stream reader terminal: receiving a command to display the navigation interface; and transmitting a request to access secondary contents of the interface, the request including a datum representative of a type of secondary contents to be streamed, the chosen image type taking into account a datum related to the streaming of the main content.

The invention claimed is: 
     
       1. A method comprising:
 managing, in a multimedia-stream reader terminal, streaming of a televisual content, called a main content, and of a navigation interface concomitantly from a telecommunication network, the navigation interface comprising regions including contents representative of real-time televisual contents available for selection, which are called secondary contents, the main content being streamed in the form of chunks having a plurality of time-variable encoding bit rates including a lower bit rate and a higher bit rate, an encoding bit rate for the main content being selected as a function of an available bandwidth of the telecommunication network, wherein a secondary content of the secondary contents available for selection has a plurality of image qualities and wherein the managing comprises, in the multimedia-stream reader terminal: 
 prior to receiving a command to display the navigation interface, defining an encoding-bit-rate threshold value, which is higher than the lower bit rate and is not to be crossed when streaming the main content and the navigation interface concomitantly, the encoding-bit-rate threshold value being chosen among the plurality of time variable encoding bit rates independently of the available bandwidth of the telecommunication network; 
 receiving the command to display the navigation interface; 
 defining an image quality chosen among said plurality of image qualities, said image quality being chosen such that the encoding bit rate-used for streaming the main content remains higher than said defined threshold value; 
 transmitting a request to access the secondary content of the interface, the request including a datum representative of the defined image quality; and 
 receiving both main content with a bit rate higher than said threshold value and the secondary content with the defined image quality. 
 
     
     
       2. The method according to  claim 1 , wherein the datum related to the streaming of the main content further comprises the encoding bit rate used for the streaming. 
     
     
       3. The method according to  claim 2 , wherein the datum related to the streaming of the main content comprises the encoding bit rate of a value chosen in such a way that the sum of an encoding bit rate requested for the secondary content and the encoding bit rate used for the main content is lower than a given maximum encoding-bit-rate value. 
     
     
       4. The method according to  claim 1 , wherein the datum related to the streaming of the main content comprises a value representative of a type of communication network used to stream the main content. 
     
     
       5. The method according to  claim 1 , wherein a type of the requested secondary content corresponds to the encoding bit rate. 
     
     
       6. An entity for managing, in a reader terminal, streaming of a televisual content, called a main content, and of a navigation interface concomitantly from a telecommunication network, the navigation interface comprising regions including contents representative of real-time televisual contents available for selection, which contents are called secondary contents, the main content being streamed in the form of chunks having a plurality of time-variable encoding bit rates including a lower bit rate and a higher bit rate, an encoding bit rate for the main content being selected as a function of an available bandwidth of the telecommunication network, wherein a secondary content of the secondary contents available for selection has a plurality of image qualities, and wherein the entity comprises:
 processor; and 
 a non-transitory computer-readable medium comprising instructions stored thereon which when executed by the processor configure the entity to: 
 prior to receiving a command to display the navigation interface, define an encoding-bit-rate threshold value, which is higher than the lower bit rate and is not to be crossed when streaming the main content and the navigation interface concomitantly, the encoding-bit-rate threshold value being chosen among the plurality of time variable encoding bit rates independently of the available bandwidth of the telecommunication network; 
 receive the command to display the navigation interface; 
 define an image quality chosen among said plurality of image qualities, said image quality being chosen such that the encoding bit rate-used for the streaming of the main content remains higher than said defined threshold value; and 
 transmit a request to access the secondary content of the interface, the request including a datum representative of the defined image quality; and 
 receiving both main content with a bit rate higher than said threshold value and the secondary content with the defined image quality. 
 
     
     
       7. The entity according to  claim 6 , wherein the entity is comprised in the reader terminal. 
     
     
       8. A non-transitory computer-readable data medium on which at least one sequence of program-code instructions has been stored, which when executed by a processor of a multimedia-stream reader terminal configure the multimedia-stream reader terminal to manage streaming of a televisual content, called a main content, and of a navigation interface concomitantly from a telecommunication network, the navigation interface comprising regions including contents representative of real-time televisual contents available for selection, which are called secondary contents, the main content being streamed in the form of chunks having a plurality of time-variable encoding bit rates including a lower bit rate and a higher bit rate, an encoding bit rate for the main content being selected as a function of an available bandwidth of the telecommunication network, wherein to a secondary content of the secondary contents available for selection has a plurality of image qualities, and wherein the managing comprises:
 prior to receiving a command to display the navigation interface, defining an encoding-bit-rate threshold value, which is higher than the lower bit rate and is not to be crossed when streaming the main content and the navigation interface concomitantly, the encoding-bit-rate threshold value being chosen among the plurality of time variable encoding bit rates independently of the available bandwidth of telecommunication network; 
 receiving the command to display the navigation interface; and 
 defining an image quality chosen among said plurality of image qualities, said image quality being chosen such that the encoding bit rate-used for the streaming of the main content remains higher than said defined threshold value; 
 transmitting a request to access the secondary content of the interface, the request including a datum representative of the defined image quality; and 
 receiving both main content with a bit rate higher than said threshold value and the secondary content with the defined image quality.
